There's an app in the game for "anonymous posting". If you attempt to use it without an internet connection it doesn't work. When you use it, it attempts to connect to 64.29.17.X for a server-assisted AI chat. Very not cool.
At the expense of suspension of (dis)belief, there should be some kind of (in-game) warning for that. "AI-powered dialogue" is very different depending upon whether it stays local or plugged into some mystery database.
